Örnekler

Aşağıdaki kod örneği, Bir Microsoft SQL Server veritabanından veri almayı ve bir denetimde GridView görüntülemeyi gösterir. Ayrıca, yeni kayıtlar eklemek için ve formunda seçili satırın GridView ayrıntılarını görmek için denetimin nasıl kullanılacağını DetailsView gösterir.

Denetimde GridView bir veri kümesi ve DetailsView belirli bir satırın ayrıntıları görüntülenir. Denetimin otomatik olarak oluşturulan Ekle düğmesine DetailsView tıklarsanız, DetailsView yeni kayıt eklemek için kullanılan farklı bir kullanıcı arabirimi gösterilir. Örnek, kayıtları eklemek için bir saklı yordam kullanır ve eklenen satırın birincil anahtarını döndürür. Saklı yordam adı özelliğinde InsertCommand ayarlanır ve özelliği StoredProcedure değerine ayarlanarak InsertCommandType saklı yordam olarak tanımlanır.

Denetim tarafından DetailsView veritabanına veri eklendikten sonra olayı OnInserted işlemek Inserted için olay işleyicisi çağrılır, eklenen satırın birincil anahtarının değeri görüntülenir ve DataBind verileri yenilemek için denetimin GridView yöntemi açıkça çağrılır.
